Answered by shreyaagarwal6oyfhcq

The cartilage rings are C-shaped because the back of the trachea presses against the esophagus. The cartilage opens at the esophagus and is replaced by connective tissue and muscle. This gives the esophagus space to allow food to be swallowed easily.

simransarkar: I liked your answer but can you explain about trachea

shreyaagarwal6oyfhcq: yes wait for a sec

shreyaagarwal6oyfhcq: trachea is a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe.

The growth rings are concentric rings, also known as annual rings. Secondary growth gives rise to these rings. Secondary growth occurs due to the activity of meristematic tissue, cambium. By counting these rings, one can determine the age of the tree.
